Hello, going to trade up my 99 deville, before HG failure, 70,000 miles. Was wondering, from what year up, should I look for so I might be able to not worry about HG's
Thanks
Do not know if this posted in the right place

There was an improvement in 2000 to the head bolts that greatly reduced the probability and another in '03 or '04.
